Frequently asked

What does Diapasón do?

It retunes your own local music to 432 Hz in real time — a warmer, gentler pitch — losslessly, right on your device. You can build a playlist, switch 432 ↔ 440 live, and export a 432 Hz copy as WAV or MP3.

Does it work offline? Is my music private?

Yes. Everything happens on your device. Nothing is uploaded, there are no accounts and no tracking, and your original files are never modified. See our Privacy Policy.

Can I play Spotify or YouTube in 432 Hz?

Diapasón plays the audio files stored on your own device. It doesn't stream from Spotify or YouTube.

Why doesn't exporting at a higher bitrate improve quality?

Audio quality can't be added back once it's gone. If your source file is 128 kbps, exporting it at 320 kbps only makes a bigger file — not a better‑sounding one. Export at or below the source bitrate.

Which devices does it run on?

Windows 10 & 11, iPhone & iPad, and Android.

If I buy it on one platform, do I get the others?

No. Diapasón is sold separately on the App Store, Google Play and Microsoft Store. One purchase covers your devices on that platform (for example, iPhone and iPad together on the App Store).

How do I export my whole playlist?

Open “My playlist”, choose “Whole playlist” in the export options, pick a format, and Diapasón converts every track to 432 Hz.
